Omnicore-cli命令一览

Omni的资料相对比较少，把一些常用命令执行结果也列出来，便于快速的了解。
omni_getallbalancesforid
取指定omni代币
Chaim:bin Chaim$ ./omnicore-cli "omni_getallbalancesforid" 1
[
{
"address": "1DUJAPA5i7biVYyZNCnckqEBEjY1Act2ct",
"balance": "100.00000000",
"reserved": "0.00000000"
},
...
为什么是一堆地址？
It returns all balances for the entire state, not just for addresses in the wallet.
omni_getallbalancesforaddress
单独取某个地址的omni代币

Chaim:bin Chaim$ ./omnicore-cli "omni_getallbalancesforaddress" "1LziTa1SYJx4bB7X8imUufQHVJVG6VUuRJ"
[{"propertyid": 1,"balance": "0.00050000","reserved": "0.00000000"}, {"propertyid": 2,"balance": "0.10000036","reserved": "0.00000000"}
]

omni_gettransaction
取交易数据

Chaim:bin Chaim$ ./omnicore-cli "omni_gettransaction" "1fc6ef3e006fce0f18d409e2a49f86472a47532913e954e4397e100a49ff0390"
{"txid": "1fc6ef3e006fce0f18d409e2a49f86472a47532913e954e4397e100a49ff0390","fee": "0.00002612","sendingaddress": "1FoWyxwPXuj4C6abqwhjDWdz6D4PZgYRjA","referenceaddress": "1CYUf3Uq3cqLswFApccRup84szbgYLq1H3","ismine": false,"version": 0,"type_int": 0,"type": "Simple Send","propertyid": 31,"divisible": true,"amount": "12.70000000","valid": true,"blockhash": "0000000000000000001647535108c3d997eeff8503e17369f3bd074fd3bd8ceb","blocktime": 1522303393,"positioninblock": 503,"block": 515635,"confirmations": 7547
}

propertyid为31，在这就是USDT了。
再取下以前测试过的地址，为什么这个地址USDT这么多？

Chaim:bin Chaim$ ./omnicore-cli "omni_getallbalancesforaddress" "1FoWyxwPXuj4C6abqwhjDWdz6D4PZgYRjA"
[{"propertyid": 31,"balance": "689041561.18427944","reserved": "0.00000000"}
]

omni_listproperties
列出propertyid的代币，可以看到propertyid=31是啥了

Chaim:bin Chaim$ ./omnicore-cli "omni_listproperties"
[{"propertyid": 1,"name": "Omni","category": "N/A","subcategory": "N/A","data": "Omni serve as the binding between Bitcoin, smart properties and contracts created on the Omni Layer.","url": "http://www.omnilayer.org","divisible": true}, {"propertyid": 2,"name": "Test Omni","category": "N/A","subcategory": "N/A","data": "Test Omni serve as the binding between Bitcoin, smart properties and contracts created on the Omni Layer.","url": "http://www.omnilayer.org","divisible": true}, ...{"propertyid": 31,"name": "TetherUS","category": "Financial and insurance activities","subcategory": "Activities auxiliary to financial service and insurance activities","data": "The next paradigm of money.","url": "https://tether.to","divisible": true},...

详细查看propertyid=31的数据：

Chaim:bin Chaim$ ./omnicore-cli "omni_getproperty" 31
{"propertyid": 31,"name": "TetherUS","category": "Financial and insurance activities","subcategory": "Activities auxiliary to financial service and insurance activities","data": "The next paradigm of money.","url": "https://tether.to","divisible": true,"issuer": "3MbYQMMmSkC3AgWkj9FMo5LsPTW1zBTwXL","creationtxid": "5ed3694e8a4fa8d3ec5c75eb6789492c69e65511522b220e94ab51da2b6dd53f","fixedissuance": false,"managedissuance": true,"freezingenabled": true,"totaltokens": "2520000000.00000000"
}

raw transaction
到这说下我研究USDT的目的，我需要进行USDT转帐交易，同时希望是在冷钱包中签名，所以需要使用原始交易数据，生成交易数据后再拿到冷钱包中进行签名，再把签名后数据拿到热钱包中发送。

以下交易步骤按网上流程尝试，可能是已经使用过的数据，借此也可以看看相关api的结果，看看我的想法可不可行。

1.读取指定地址的UTXO（listunspent）

这个命令是比特币的命令，可以在这了解这些命令

Chaim:bin Chaim$ ./omnicore-cli "listunspent" 0 999999 '["1FoWyxwPXuj4C6abqwhjDWdz6D4PZgYRjA"]'
[
]

基于比特币UTXO的方式，并不是能在一个节点上列出任意地址的余额，也无法列出任意地址的UTXO，得先把地址导入钱包。
节点钱包操作

importaddress 1FoWyxwPXuj4C6abqwhjDWdz6D4PZgYRjA

2.构造发送代币类型和代币数量数据（payload）
指定omni代币和数量

Chaim:bin Chaim$ ./omnicore-cli "omni_createpayload_simplesend" 31 "1.0"
000000000000001f0000000005f5e100

3.构造交易基本数据（transaction base）
指定从哪个源地址（UTXO中txid和vout）转移比特币

Chaim:bin Chaim$ ./omnicore-cli "createrawtransaction" '[{"txid":"9fd770cf78e48f562378e210c162be725d76c12e7dfcb682a210d91d6f23ffff","vout":1},{"txid":"7bdb7918de91036223e461fed4291f691267087a40e55d3e7b3fbcfef741ffff","vout":1}]' '{}'
0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff0000000000

4.在交易数据中加上omni代币数据
这一步把omni代币数据也组合到交易数据上

Chaim:bin Chaim$ ./omnicore-cli "omni_createrawtx_opreturn" "0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff0000000000" "000000000000001f0000000005f5e100"
0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff010000000000000000166a146f6d6e69000000000000001f0000000005f5e10000000000

5.在交易数据上加上接收地址

Chaim:bin Chaim$ ./omnicore-cli "omni_createrawtx_reference" "0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff010000000000000000166a146f6d6e69000000000000001f0000000005f5e10000000000" "1Njbpr7EkLA1R8ag8bjRN7oks7nv5wUn3o"
0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff020000000000000000166a146f6d6e69000000000000001f0000000005f5e10022020000000000001976a914ee692ea81da1b12d3dd8f53fd504865c9d843f5288ac00000000

6.在交易数据上指定矿工费用
指定矿工费用和UTXO数据（txid、vout、scriptPubkey、value），也可以改变找零地址

Chaim:bin Chaim$ ./omnicore-cli "omni_createrawtx_change" "0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff020000000000000000166a146f6d6e69000000000000001f0000000005f5e10022020000000000001976a914ee692ea81da1b12d3dd8f53fd504865c9d843f5288ac00000000" '[{"txid":"9fd770cf78e48f562378e210c162be725d76c12e7dfcb682a210d91d6f23ffff","vout":1,"scriptPubKey":"76a914a25dec4d0011064ef106a983c39c7a540699f22088ac","value":0.00000546},{"txid":"7bdb7918de91036223e461fed4291f691267087a40e55d3e7b3fbcfef741ffff","vout":1,"scriptPubKey":"76a914a25dec4d0011064ef106a983c39c7a540699f22088ac","value":0.00000546}]' "1FoWyxwPXuj4C6abqwhjDWdz6D4PZgYRjA" 0.0006
0100000002ffff236f1dd910a282b6fc7d2ec1765d72be62c110e27823568fe478cf70d79f0100000000ffffffffffff41f7febc3f7b3e5de5407a086712691f29d4fe61e423620391de1879db7b0100000000ffffffff020000000000000000166a146f6d6e69000000000000001f0000000005f5e10022020000000000001976a914ee692ea81da1b12d3dd8f53fd504865c9d843f5288ac00000000

7.交易签名
这步是比特币的签名命令

Chaim:bin Chaim$ ./omnicore-cli "signrawtransaction" "0100000002de95b97cf4c67ec01485fd698ec154a325ff69dd3e58435d7024bae7f69534c20000000000ffffffffb3b60aaa69b860c9bf31e742e3b37e75a2a553fd0bebf8aaf7da0e9bb07316ee0200000000ffffffff036a5a0d00000000001976a914c6734676a08e3c6438bd95fa62c57939c988a17b88ac0000000000000000166a146f6d6e690000000000000002000000000098968022020000000000001976a914ee692ea81da1b12d3dd8f53fd504865c9d843f5288ac00000000"
{"hex": "0100000002de95b97cf4c67ec01485fd698ec154a325ff69dd3e58435d7024bae7f69534c20000000000ffffffffb3b60aaa69b860c9bf31e742e3b37e75a2a553fd0bebf8aaf7da0e9bb07316ee0200000000ffffffff036a5a0d00000000001976a914c6734676a08e3c6438bd95fa62c57939c988a17b88ac0000000000000000166a146f6d6e690000000000000002000000000098968022020000000000001976a914ee692ea81da1b12d3dd8f53fd504865c9d843f5288ac00000000","complete": false,"errors": [{"txid": "c23495f6e7ba24705d43583edd69ff25a354c18e69fd8514c07ec6f47cb995de","vout": 0,"scriptSig": "","sequence": 4294967295,"error": "Input not found or already spent"}, {"txid": "ee1673b09b0edaf7aaf8eb0bfd53a5a2757eb3e342e731bfc960b869aa0ab6b3","vout": 2,"scriptSig": "","sequence": 4294967295,"error": "Input not found or already spent"}]
}

在这发现一个问题，交易签名时对input进行了判断，而不是我以为的只是用对应的私钥进行签名而已。
重新走一遍这个生成原始交易的流程，保证input存在且unspent，但没有私钥进行签名看看是什么结果？
USDT钱包基本没有可用的，也就Omnicore这边可以用，要再搭私链又太麻烦费事，只能从交易所提点USDT出来测试了。
继续走一遍生成原始交易数据的流程：

这次执行到发送交易了，只是发送交易出错，据说是费用太低，其实我是特意做测试的，因为这个地址上除了转USDT带来的0.00000546BTC之外，根本就没有比特币，指定费用再大也没用！重新测试了一下指定更大的交易费错误也是一样，看来这个错误就是说BTC不够了！
还得转点BTC到这个地址，这样所有的流程又得重来，因为UTXO变了，哭...

检验其正确性 http://chainquery.com/bitcoin-api/sendrawtransaction
不过这次交易应该是成功了，等待确认吧！
在btc.com能查到这笔交易了，不过它上面有个交易加速，这个加速是怎么实现的呢？我给它钱，它怎么给矿工钱？
交易费设得太低了，不知道能不能成交了！
不过以上流程基本验证USDT转帐也可以使用热钱包建立原始交易，冷钱包签名的模式了！

原理上是和比特币是一样的，只是验证还是必需自己做一下！
